Similarly, it is possible to provide ridge buster cylinder 236 handles ridge buster 230. Hydraulic pump 238 is operably linked on electromotor 224 to provide pressurized hydraulic fluid via flexible pipe 240 to hydraulic cylinder 232,234,236.
Go back to Fig. 1, LCD102 operationally with controller 108 communication. LCD102 can be any suitable LCD known in the art. Such as, LCD102 can be configured as receiving user's input and showing the touch-screen user interface 104 of output. LCD102 is placed in the inner space 227 limited by the control cabinl pulpit 226 on machine 20.
In one embodiment, LCD102 includes screen 110. Screen 110 includes multiple viewing area 116. Such as, in one embodiment, the screen 110 of LCD102 includes the first viewing area 116a and the second viewing area 116b. In other embodiments, can there be more multiple-aspect territory 116.
One or more icons 118 can be displayed in the first viewing area 116a. In one embodiment, this icon 118 can be system instruction or warning instruction. Such as, this instruction can provide following bulletin for operator: uses stopping brake, it is achieved apparatus locks, and there is exhaust system fault, level of fuel step-down, and operator's seat belt unclamps, exist turn to, charging system or engine failure etc. When being shown in the first viewing area 116a or other viewing areas 116 arbitrary, icon 118 is shown on LCD102 with icon intensity level.
One or more images 120 can be displayed in the second viewing area 116b. Because LCD102 is typically not optionally dimmed at regional area as the display using light emitting diode, these images 120 will be shown on LCD102 with the output intensity level identical with icon intensity level. In one embodiment, this image 120 may include but be not limited to, fuel metering, temperature, speed, network for location, the degree of packing, luminescence or other features and below figure picture, represent that left and right turn signal is opened, realize shovel to float, realize polling power controlling, adopt differential lock, operate machine 200 with economic model or self shifter pattern, it is achieved capstan winch lock etc.
Fig. 3 illustrates the schematic diagram of exemplary L CD102. In this embodiment, LCD102 includes the screen 110 with first, second, and third viewing area 116 (a-c). Icon 118 can be displayed in the first viewing area 116a. Image 120 (a-c) is shown in the second viewing area 116b. In some embodiments, one or more icons 118 can be displayed in the 3rd viewing area 116c of LCD102. 3rd viewing area 116c may differ from the first and second viewing areas 116 (a-b). It is shown in the icon 118 in the 3rd viewing area 116c can icon intensity level show.
In some embodiments, icon 118 does not have overlap. Icon 118 shows with icon level intensity level and image 120 (a-c) is shown on LCD102 with icon intensity level. In some embodiments, icon intensity level can be the LCD102 maximum brightness level allowed. In other embodiments, icon intensity level can be relatively low intensity level, for example such as, time on the whole to LCD102 supply smaller power. In any case, icon 118 and image 120 (a-c) will show (when not adopting mask image 122) with same intensity level.
With reference now to Fig. 4, in order to reduce the visible brightness level of the LCD102 that observer sees, one or more mask image 122 optionally show that (on LCD102) is each image 120 (a-c) above. In this scheme, each lower image 120 (a-c) can synthesize intensity level and see through mask image 122. This synthesis intensity level (observer as synthesis (image) 124 sees, composograph 124 is made up of lower image 120 and (covering) mask image 122) is less than icon intensity level and provides the local of lower image 120 dimmed visual effect on LCD102. Dimmed change should achieve that by the voltage level for illuminating the valve pervious to light element of LCD102 from behind in this local. This local dimmed (application via mask image 122) does not make each independent valve pervious to light element appearing dark (or control) of LCD102 to realize equally; Although this dimmed (or the control) of each independent valve pervious to light element of LCD102 may result in the power consumption of minimizing, but it is not result in the application of independent transparent mask image 122 (overlay image), is appreciable through this image lower image 120.
As it has been described above, Fig. 4 illustrates an embodiment, wherein the local of the mask offer image of image 120 is dimmed. Especially, Fig. 4 illustrates the schematic diagram of same exemplary L CD102 as seen in Figure 3, only now also uses mask image 122. In the diagram, mask image 122 is shown in the image 120 (a-c) in the second viewing area 116b above. Mask image 122 is dark-toned in color, and is rendered as transparent, and therefore each lower image 120 (a-c) can be seen through mask image 122 on LCD102. Shade is such as it may be that gray tone, brown tune etc., to produce dark superimposed images effect. Mask image 122 is shown on the top of one or more image 120 (a-c), therefore covers the image 120 (a-c) on the second viewing area 116b. The synthesis 124 of each lower image 120 (a-c) and mask image 122 makes each lower image 120 (a-c) with the synthesis intensity level less than icon intensity level visible (through mask image 122) on LCD102. Such as, in one embodiment, the first icon intensity level is approximately the twice of synthesis intensity level numerical value. In other embodiments, synthesis intensity level numerical value can be about 80 the percent of the first icon intensity level. Other percentage ratios can be envisioned, for instance, synthesis intensity level can in the scope of about the 95% of icon intensity level to about 5%.
As shown in Figure 4, the first image 120a, the second image 120b and the three image 120c are usually not overlapping and be shown in the second viewing area 116b. In other embodiments, they can overlap. In an embodiment shown in fig. 4, a mask image 122 covers the first image 120a, the second image 120b and the three image 120c. In the diagram, mask image 122 is illustrated as and covers whole second viewing area 116b. In other embodiments, all as shown in Figure 5, the first mask image 122a can cover the first image 120a, the second mask image 122b can cover the second image 120b, and the 3rd mask image 122c can cover the 3rd image 120c.
In other embodiments, mask image 122 can cover some in the second viewing area 116b rather than all images 120. Alternatively, in some embodiments, mask image 122 can only cover a part of the second viewing area 116b, therefore makes another part (and any image 120 being shown in this another part) of the second viewing area 116b not have mask image 122. Such as, as shown in Figure 8, mask image 122 covers a part of the first and second images 120 (a-b) and the second viewing area 116b, but does not cover the 3rd image 120c and do not cover the framing image 120d surrounding the 3rd image 120c.
In any case, image 120 each shows with the synthesis intensity level less than icon intensity level when being covered by mask image 122. If image 120 is not covered by mask image 122, it will show with the output intensity level identical or essentially identical with icon intensity level.
For clarity sake, next will arrange in conjunction with the image 120 shown in Fig. 4 and mask image 122 and be described, but it is understood that, ensuing can also be used for alternate embodiments, for example, those described in such as Fig. 5 and 8. In one embodiment, the vision dimming levels in image 120 and/or LCD102 region can by using associated, to have different transparency different mask image 122 to reach. Such as, in an arrangement, user wishes to make the image 120 in the second viewing area 116b of LCD102 dimmed. For this, mask image 122 can be displayed in above image 120. In one embodiment, mask image 122 is the black with high degree of transparency, and therefore the mask image 122 of the permeable display of downside image 120 is visible, but for the observer slightly dimmed (synthesis intensity level is less than icon intensity level). If requiring that image 120 is dimmed further, controller 108 can be removed current mask image 122 and replace with another less transparent mask image 122. Therefore, the synthesis 124 of lower image 120 and less transparent (replacement) mask image 122 is for the observer darker than aforementioned synthesis 124 (in other words, the newly synthesized intensity level of lower image 120 and replacement mask image 122 is less than the previously synthesized intensity level of image 120 and previous mask image 122). If requiring less dimming, controller 108 can be removed mask image 122 and alternatively have another mask image 122 of bigger transparency.
Some image 120 being it desired in the second viewing area 116b is dimmed more or less, and current mask image 122 can be alternatively had another mask image 122 of difformity or overlay area by controller 108. Such as, controller 108 generally makes the image 120 in the second viewing area 116b dimmed (display via lower floor's mask image 122), such as engine temperature image. If engine temperature (or other operating parameters relevant with image 120) is close to concern scope, currently displaying mask image 122 (causing that engine temperature image is dimmed) can be replaced with mask image 122 by controller 108, but this image can cover other images 120 some or all of in the second viewing area 116b not cover engine temperature image, or provides bigger transparency therefore to have engine temperature image 120 dimer compared with other images 120 in the second viewing area 116b on engine temperature image.
For clarity sake, next it is described arranging in conjunction with the image 120 shown in Fig. 4 and 6 and mask image 122, but it is understood that, ensuing can also be used for alternate embodiments, for example, those described in such as Fig. 5 and 8, wherein shown mask image 122 does not cover whole second viewing area 116b. In some embodiments, the mask image 122 being shown in the second viewing area 116b can be the independent mask image 122 of multiple overlap, its lower image 120 (stacking) stacked on top of each other with the bottom (or bottom) of " stacking " 126 being positioned at mask image 122. One embodiment of this scheme is illustrated in Fig. 6, and two of which mask image 122 (a-b) has been used in the second viewing area 116b. Each in these multiple mask image 122 (a-b) is positioned to cover lower image, but and each be dark-toned in color be transparent, multiple mask image 122 (a-b) that therefore lower image 120 can pass through in stacking 126 are seen. In some embodiments, each mask image 122 in stacking 126 has identical transparency. In other embodiments, transparency between mask image 122 can be different in stacking 126. Stacking 126 can include two or more mask image 122. Owing to being used in each additional mask image 122 (a-b) above lower image 120, the synthesis intensity level of lower image 120 reduces. In one embodiment, each additional (continuously) mask image 122 (a-b) application in multiple mask image 122 of stacking 126 in a step-wise fashion (inasteppedmanner) reduces the synthesis intensity level of LCD102 levels image. Along with the number of mask image 122 increases in stacking 126, synthesis intensity level reduces and in stacking 126, the change of synthesis intensity level between the application of each mask image 122 becomes less. In some embodiments, some in multiple mask image 122 are shade or less transparent compared with other so that when this deeper mask image 122 is used in image 120 above, synthesis intensity level aspect has more noticeable change.
Controller 108 can include processor 112 and memory unit 114. Controller 108 can with LCD102, user interface 104 and optical sensor 106 operationally communication. Processor 112 can be microprocessor or other processors known in the art.
Processor 112 can be configured to perform instruction and produce control signal, for making one or more icon 118 show with icon intensity level in the first viewing area 116a of LCD102, make image 120 show in the second viewing area 116b of LCD102, and reduce, by making one or more mask image 122 be shown in above image 120, the visible brightness showing image 120. This instruction can read in or be attached in the computer-readable medium of such as memory unit 114 or to be located at processor 112 outside. In an alternative embodiment, hardwire loop can be used for replacing software instruction or in connection performs control method.
Terminology used here " computer-readable medium " refers to any permanent media or participates in providing the instruction combination of media for performing to processor 112. This medium can include all computer-readable mediums except temporary transient transmitting signal. The common version of computer-readable medium includes, such as, other media any that floppy disk, flexible disk (-sc), hard disk, tape or other magnetic mediums any, CD-ROM, other optical mediums any or computer processor 112 can thus read.
Controller 108 is not limited to a processor 112 and memory unit 114. Controller 108 can be some processors 112 and memory unit 114.
In one embodiment, controller 108 can send from LCD102 and receive signal. This signal can be the result of user's input user interface 104 or by optical sensor 106 ambient light levels of sensing in control cabinl pulpit 226 (or elsewhere). Controller 108 is also configured to obtain information sum from memorizer 114 and according to this and information and data is stored in memorizer 114.
In some embodiments, the dimming of operator controlled imaged 120. Such as, operator can optionally reduce the output intensity level (by using mask image 122) of image 120, optionally increase and decrease the synthesis intensity level (by increasing or removing mask image 122) of synthesis (image) 124/ lower image 120, or remove mask image 122 to show image 120 via the input (" operator's input ") of user interface 104 with icon intensity level. In this embodiment, the operator received inputs the transparency determining mask image 122 or the number of the overlapping mask image 122 being shown on image 120 top. In other embodiments, the image 120 (by using one or more mask image 122) on LCD102 can be dimmed to the synthesis intensity level of acquiescence by controller 108 automatically according to the ambient light levels (" sensor input ") that optical sensor 106 is measured in control cabinl pulpit 226. Cause this operator that LCD102 epigraph 120 dims to input or sensor input is referred to alternatively as " dimming input ".
